Dry eye syndrome

My eyes were stinging and I was crying a lot, so I went to the ophthalmologist.

He said there is a scratch in the right eye and diagnosed it as dry eye syndrome.

After applying artificial tears and doing eye compresses, I went to the ophthalmologist after a week. My condition improved, but my tears wouldn't stop, so I had my tear ducts blocked.

I went back to the hospital after a month, and the scratch had disappeared, so I received artificial tear medication and was told to come back in six months.

It's gotten better, but since then, I often have small crusts in my eyes.

I'm curious about the reason why I suddenly have a lot of small eye crusts, possibly due to dry eyes or artificial tears.

When going out, I have to check frequently because of eye crusts.
